Problem Definition: Problem Definition Given a still picture, we generate a walk-through animation with water surface reflection while allowing foreground objects to move.
Previous Work: Previous Work Stochastic Motion Textures [Chuang et al. 05] Image-based rendering [Chen et al. 95, Gortler et al. 96, Kang and Shin 04, Hoiem et al. 05] Extension of TIP [Kang et al. 01] Tour Into the Picture [Horry et al. 97]

Slide12: Water Surface Movement approximated objects Interaction with objects such as ground, rocks, and boats
geometry of water surface and interacting objects RealFlow
Slide13: Rendering For each pixel, one ray is shot
Intersection check order
Foreground (lower depth => higher depth)
